Problem with parallel loading

I'm working with a board that has a problem with parallel loading. It's A Spartan 3 FPGA with an XCF08P flash.The firmware loads without issues when serial configuration is set (M bits: "000") . However, it doesn't work with parllel loading (M bits: "110").

Re: Problem with parallel loading

There are a number of possible causes for such problems. You should post the board schematics if you want to pursue this problem further in these forums, so we can see a bit more of what you see.
